This is a retarded take, guys like the ones you listed are never going to be grad transfers, we should absolutely take any grad transfer we think can help the team at all regardless of position.
Best case scenario I can think of right now adding:
Lewis WR
Hookfin OL
Cunningham JUCO OL
Johnson JUCO LB
Catalon DB
Warren DE
Sanders RB
McCoy WR
that gets you to 290.01(probably good for 4-5 final ranking)
sub out Sanders for Cain and it gets you 286.01(probably 6-8)
It's all a gamble either way, but staying on he at least has a chance to graduate.
He can come back and get that degree any time he wants, we’ve had numerous players follow this path over the years.
Almost all of the sites have indirectly said the 1st shhhh is Gbenda, apparently he’s waiting on a commitment video, and TFB and I think 247 have said the most recent one is a 2019 defensive player.
Almost assuredly Gbenda and Owens
